[Impact of COVID-19 on oncological surgery of the upper gastrointestinal tract]. / Auswirkungen von COVID-19 auf die onkologische Chirurgie des oberen Gastrointestinaltrakts.

BACKGROUND: The outbreak of the coronavirus disease 2019 (COVID-19) pandemic imposed limitations for elective surgery, impacting the associated hospital standards worldwide. As certain treatment windows must be adhered to in oncological surgery, the limited intensive care unit (ICU) capacity had to be critically distributed in order to do justice to both acutely ill and oncology patients. This manuscript summarizes the impact of COVID-19 on the management of oncological surgery of the upper gastrointestinal tract and particularly esophageal surgery in German medical centers. MATERIAL AND METHODS: A survey of German centers for esophageal surgery was performed on the impact of COVID-19 on operative management for esophageal surgery during the first lockdown. After inspection, assessment, critical analysis and interpretation, the results were compared to the international literature. RESULTS AND DISCUSSION: Initial recommendations of international societies warned for caution and restraint regarding interventions of the upper gastrointestinal tract that were not absolutely necessary. Oncological surgery should be performed under strict restrictions, especially only after negative testing for COVID-19 and only with sufficiently available personal protective equipment for the personnel. Furthermore, minimally invasive procedures were preferably not recommended. In diseases with alternative treatment options, such as definitive chemoradiotherapy of esophageal squamous cell carcinoma, these should be given priority when possible. In the further development of the pandemic, it was shown that due to a high standardization of preoperative management, postoperative results comparable to pre-pandemic times could be achieved particularly with respect to the diagnostics of infections.

The influence of the SARS-CoV-2 pandemic on esophagogastric cancer services: an international survey of esophagogastric surgeons.

BACKGROUND: Several guidelines to guide clinical practice among esophagogastric surgeons during the COVID-19 pandemic were produced. However, none provide reflection of current service provision. This international survey aimed to clarify the changes observed in esophageal and gastric cancer management and surgery during the COVID-19 pandemic. METHODS: An online survey covering key areas for esophagogastric cancer services, including staging investigations and oncological and surgical therapy before and during (at two separate time-points-24th March 2020 and 18th April 2020) the COVID-19 pandemic were developed. RESULTS: A total of 234 respondents from 225 centers and 49 countries spanning six continents completed the first round of the online survey, of which 79% (n = 184) completed round 2. There was variation in the availability of staging investigations ranging from 26.5% for endoscopic ultrasound to 62.8% for spiral computed tomography scan. Definitive chemoradiotherapy was offered in 14.8% (adenocarcinoma) and 47.0% (squamous cell carcinoma) of respondents and significantly increased by almost three-fold and two-fold, respectively, in both round 1 and 2. There were uncertainty and heterogeneity surrounding prioritization of patients undergoing cancer resections. Of the surgeons symptomatic with COVID-19, only 40.2% (33/82) had routine access to COVID-19 polymerase chain reaction testing for staff. Of those who had testing available (n = 33), only 12.1% (4/33) had tested positive. CONCLUSIONS: These data highlight management challenges and several practice variations in caring for patients with esophagogastric cancers. Therefore, there is a need for clear consistent guidelines to be in place in the event of a further pandemic to ensure a standardized level of oncological care for patients with esophagogastric cancers.
